6 Note: Dramm offers an instructional video on our website. Please watch this before using your machine. How Does My Autofog MLVH-10A Work? The Dramm Autofog applys chemicals under the low-volume (LV) principle. This means that the same amount of active chemical is applied to a given area, but the chemical is diluted into reduced amounts of water. Because LV application is very efficient, many users have found that lower volumes of chemical can be used with the same results. The Mini Autofog MLVH-10A will require a minimum of 2 liters of water and the chemical to treat 5,000 square feet. If less than 5,000 square feet is treated, a minimum of 2 liters of water is still used. The specially designed solution tank and agitator prevents concentrated chemicals from precipitating. According to conventional high-volume (HV) spraying methods, approximately 20 gallons of water (diluent) plus the chemical is needed to treat 5,000 square feet. LV application is only possible when extremely fine particles are produced. The patented nozzle design of the Mini Autofog MLVH-10A produces particles which will range in size from.5 to 10 microns in diameter. Air enters the nozzle from the oil-less compressor and then exits the nozzle at super sonic speeds. This movement of air creates a venturi that draws solution from the chemical tank. As the solution exits the nozzle it is micronized into billions of tiny particles. The micronized chemical particles stay suspended for up to 6 hours and are distributed by horizontal airflow fans (HAF) and natural air currents. The Mini Autofog MLVH-10A features manual starting and a timer for automatic shut-down. Other features include a safety valve on the compressor to release any abnormal pressure build-up. The motor which drives the compressor is supplied with a grounded electrical cord set and is protected from overheating with a thermal fuse that disconnects power to the entire sprayer. The Mini Autofog MLVH- 10A now has a redesigned frame and handle to ease in its transportation in small greenhouses and storage facilities. 7 Dramm Autofog MLVH-10A Manual

7 Precautions / Pre-Operation Checklist Treatment Area A. For the most effective performance, the treatment area must be air tight. Take time to repair any broken glass, torn poly and gaps or openings in vents and door frames. B. The entire treatment area should be vacant. No humans or pets should be present. C. It is recommended that the application process take place at the end of the day. Secure the treatment area and post hazard signs before spraying. D. Avoid spraying when the temperature is over 85 F in the treatment area or when relative humidity exceeds 85%. E. When utilizing horizontal airflow fans (HAF), run them for 1/2 hour longer than actual spraying time. F. Follow all EPA Guidelines regarding the application of chemicals. Compressor/Sprayer A. Test run the MLVH-10A with clear water for 1-2 minutes. Observe the spray quality. B. The discharge volume rate of clean water is approximately 45 cc / minute. When testing the unit, pull the suction hose out of the solution tank and place it in a graduated cylinder (fill it with 90 cc of clean water). The cylinder should be empty after a 2 minute test run. Be sure to check the discharge volume rate regularly to assure best results. C. Observe the operating pressure. The gauge will read PSI. NOTE: Check for leaks in the piping when the pressure is too low. Eliminate clogs if the pressure is too high. Pressure readings may vary from location to location. Small differences are inconsequential. D. Cold weather operation: When the temperature falls below 32 F run the compressor in a warm environment before placing the MLVH-10A assembly in the area to be treated. The bearing grease may harden in very cold temperatures causing the compressor to not preform properly. Unless absolutely necessary, do not operate the MLVH-10A in sub 25 F weather. E. You will get an accurate output volume if the nozzle cap is closed completely and then returned to match the red check marks. See diagram below. NOTE: Output volume will vary cc/min. for notch in the nozzle cap. Clockwise: Output INCREASES Counterclockwise: Output DECREASES each NOTE: Check the O-ring located inside the nozzle cap for wear or damage. Replace if necessary WARNING: The standard model Autofog uses a nozzle that is manufactured with brass components. The use of oxidizers will damage this nozzle within several applications. If you plan to use oxidizers in your Autofog, CONTACT DRAMM BEFORE THE FIRST USE OF YOUR MACHINE to purchase a stainless steel nozzle at a reduced cost. After your machine has been used, Dramm cannot accept the original nozzle back for credit. Dramm Autofog MLVH-10A Manual 8

8 Preparation of Chemical Mixture and Application 1. Determine the treatment area size in square feet. NOTE: A minimum of 2 liters of water should be added to the active chemical when treating less than 5,000 square feet. More water should be added to dilute larger volumes of chemical (to a 15 to 1 ratio). 2. Calculate the chemical amount. Example: Labeled chemical rate per 100 gallons is 16 ounces. We will first calculate a rate for 10,000 square feet. Low Rate: 16oz. X 0.20 = 3.2oz. (for 10,000 square feet) High Rate: 16oz. X 0.35 = 5.6oz. (for 10,000 square feet) NOTE: Divide the rate per 10,000 square feet by 2 for the rate per 5,000 square feet. If you are treating areas less than 5,000 square feet, make the rate calculation for 5,000 square feet and reduce that amount proportionately. Contact the Dramm Service Department at or if you have any questions. 3. Calculate the water volume for at least a 15 to 1 ratio for wettable powder and flowable formulations. Mix water with chemical in the mixing pitcher. Pour the mixture into the solution tank through the strainer. Eliminate dirt and globs of chemical that may clog the nozzle. When using wettable powders, make a lumpfree slurry of the powder to wet it completely and then add the remaining portion of water. For ECs use a 10:1 dilution ratio. 4. Position the MLVH-10A for spraying. 5. Install the solution tank on the sprayer and insert the nozzle suction tube. Make sure the suction tube reaches the bottom of the tank. When a full chemical tank is loaded onto the MLVH-10A, do not move the machine to avoid spilling the chemical solution. 6. Connect the MLVH-10A to a 120V 60HZ power source and set the timer by rotating past and then returned to the desired spraying time. The spraying process begins immediately vacate the treatment area. NOTE: Always wear protective clothing, gas mask, hood, gloves and boots when mixing chemicals and using the MLVH- 10A. Application of Chemicals 1. WARNING: All EPA Guidelines on the handling, application and re-entry periods for chemicals must be adhered to. Only crops which are listed on the chemical label should be treated. 2. Labeled chemical rates are stated in amounts of chemical to be diluted into 100 gallons of water. Most chemical labels do not advise how much of the spray concentrate should be applied to a given area. 3. Greenhouse growers apply from 25 to 300 gallons of spray concentrate per 10,000 square feet, the average high volume application is gallons per 10,000 square feet. 4. The MLVH-10A is a low-volume applicator. Low volume means application of chemical in a very concentrated solution. The same amount of chemical is applied to a given area as conventional spraying, but in greatly reduced quantities of water. This is possible since low volume equipment produces very small particle sizes (0.5 to 10.0 microns) versus conventional spray particles of 100 to 400 microns. 5. If you would normally spray 25 gallons of solution into 10,000 square feet of area you are applying 25% of the chemical mixed in 100 gallons of water. (Per labeled rate per 100 gallons). 6. The charts starting on the following page will help you calculate the proper chemical amounts and water volumes. 9 Dramm Autofog MLVH-10A Manual

11 Spraying Procedure 1. Vacate the treatment area, secure all entry ways and post hazard signs. 2. Prepare the chemical solution. See page 10 for dilution rate details. Be sure that the solution is free of clumps of chemical that may clog the nozzle. Use a whisk or blender to make a smooth paste of wettable powder solutions. Check that the suction tube screen is in place in the tank. Pour the solution through the large solution strainer/ funnel assembly to eliminate any unmixed chemical or debris. 3. Plug in the main power cord. Notice the power lamp illuminated on the control panel. 4. Set the timer. Turn the dial past, then return to the desired operation time. The MLVH-10A will begin to spray, vacate the treatment area immediately. 5. If horizontal airflow fans are used, allow them to run a half hour longer than the predetermined spray time. 6. In order to allow all of the spray particles to settle, do not re-enter the treatment area for a minimum of 6 hours after the MLVH-10A has completed its operation. Keep the structure airtight. However, if it is necessary to enter the treatment area during application, only do so in a full spray suit, boots, gloves, hood and respirator. 7. After spraying, ventilate the treatment area with fresh air and clean the MLVH-10A thoroughly. Follow all EPA Guidelines for re-entry. DISCHARGE TIMES FOR MLVH-10A Timer Settings The MLVH-10A should be allowed to run for a half hour after all chemical has been expelled into the air. See the chart below for approximate amount of time it takes to expel chemicals. These times were compiled with clear water - the expulsion time time may exceed these guidelines when mixed with chemicals. Times may vary due to the consistency of solution being sprayed. Thicker solutions may take longer to discharge. A video on programming your timer is available on How To Set The Timer our website. 1. Plug the AutoFog into the appropriate power source. 2. Set the clock to the correct time. The timer is a 24 hour timer for accuracy between day and night. 3. Determine the spray starting time and stopping time. 4. Flip ALL of the pins between the starting and stopping time to the OUTSIDE. (see photo below) 5. The AutoFog will run only during the time that the pins are flipped to the outside of the clock. DO NOT FLIP THE START TIME AND STOP TIME ONLY. Each pin represents 15 minutes of time. 6. The AutoFog is now ready and will begin fogging at the appropriate time. Make sure the treatment area is secure and will be empty of all personnel at that time. NOTE: Remember to add a half hour to the spraying time when setting the timer.

20 Troubleshooting 1. The spray pattern exits the nozzle in short bursts it should exit as a steady stream. A. The nozzle cap is not secure or properly lined up. Screw it on completely and then turn the cap counter clockwise so the two check marks on the nozzle line up. Check the nozzle calibration for 45cc/minute output rate. See diagram below. D. The nozzle and/or solution tank may be clogged with chemical residue. Soak the nozzle overnight, then clean the inside of the nozzle. E. The suction tube may be clogged or damaged. With a gloved hand, cover the nozzle tip. This reverses the flow of air and blows the suction tube clean of any debris. Remove and clean the tube or replace it if necessary. See the diagram below. Suction Tube Nozzle Cap Checkmark Checkmark B. The nozzle cap has an O-Ring inside which may be damaged. Replace the O-Ring if it is cracked, broken or in some way damaged. C. Inspect the suction tube for clogging or damage. To remove the suction tube from the nozzle first loosen the nut that holds the tube to the nozzle. Now, pull the tube out of the nozzle. Notice the metal sleeve on the tube, inspect it carefully. In most cases the sleeve must be replaced if it is damaged, dented, bent or cracked. NOTE: ALWAYS wear a glove when covering the nozzle. F. The suction tube is above the surface of the solution in the tank. Make sure the suction tube is pushed down completely. G. The filter at the bottom of the stainless steel suction tube is clogged and needs cleaning. Inspect the entire suction tube for clogging.
